Java.lang.Boolean Class
Java Boolean Class
The Boolean class in the Java.lang package encapsulates a value of the primitive type boolean in an object. A single field of type boolean is included in a Boolean object.
This class also has a number of methods for converting a boolean to a String and a String to a boolean, as well as additional boolean-related constants and methods.
Class declaration
The java.lang.Boolean class is declared as follows:
public final class Boolean
extends Object
implements Serializable, Comparable<Boolean>
Fields
| Sl No. | Fields & Description |
|---|---|
| 1. | static Boolean FALSE The Boolean object corresponds to the primitive value false. |
| 2. | static Boolean TRUE The Boolean object corresponds to the primitive value true. |
| 3. | static Class<Boolean> TYPE The Class object represents the primitive type boolean. |
java.lang.Boolean Methods
The following are the methods available in the Boolean class:.
| S.N | Methods & Description |
|---|---|
| 1. | boolean booleanValue() Returns the value of this Boolean object as a boolean primitive. |
| 2. | static int compare(boolean x, boolean y) Compares two boolean values. |
| 3. | int compareTo(Boolean b) Compares this Boolean instance with another. |
| 4. | boolean equals(Object obj) Returns true if and only if the argument is not null and is a Boolean object that represents the same boolean value as this object. |
| 5. | static boolean getBoolean(String name) Returns true if and only if the system property named by the argument exists and is equal to the string “true”. |
| 6. | int hashCode() Returns a hash code for this Boolean object. |
| 7. | static int hashCode(boolean value) Returns a hash code for a boolean value; compatible with Boolean.hashCode(). |
| 8. | static boolean logicalAnd(boolean a, boolean b) Returns the result of applying the logical AND operator to the specified boolean operands. |
| 9. | static boolean logicalOr(boolean a, boolean b) Returns the result of applying the logical OR operator to the specified boolean operands. |
| 10. | static boolean logicalXor(boolean a, boolean b) Returns the result of applying the logical XOR operator to the specified boolean operands. |
| 11. | static boolean parseBoolean(String s) Parses the string argument as a boolean. |
| 12. | String toString() Returns a String object representing this Boolean’s value. |
| 13. | static String toString(boolean b) Returns a String object representing the specified boolean. |
| 14. | static Boolean valueOf(boolean b) Returns a Boolean instance representing the specified boolean value. |
| 15. | static Boolean valueOf(String s) Returns a Boolean with a value represented by the specified string. |
